[0002] A switch is a piece of network hardware that receives and forwards data to a target device through message exchange. It can provide an exclusive electrical signal path for any two network nodes connected to the switch, and can provide more connection ports in the sub-network, thereby connecting different devices on the computer network. A switch has multiple ports, each of which has a bridging function and can connect a local area network or a high-performance server or workstation. In fact, a switch is sometimes called a multi-port bridge.

[0003] The patent with the patent authorization announcement number CN212970620U discloses a switch, which sets an air inlet on the front panel of the switch and an air outlet on the rear panel. The fan module draws air from the rear panel to form an air duct from the front panel to the rear panel, thereby increasing the amount of cold air flowing through the heat sink, thereby achieving the purpose of increasing the heat exchange ratio of the heat sink. However, the switch provided by the patent still has shortcomings in actual use. It uses a single fan module to dissipate heat from the electrical components inside the chassis, and its heat dissipation effect is poor, which cannot meet the situation where rapid cooling is required.

[0004] Therefore, it is necessary to provide a high temperature resistant switch with efficient heat dissipation. Utility Model Content

[0005] In order to overcome the disadvantage that the switch provided by the existing patent uses a single fan module to dissipate heat for the electrical components inside the chassis, and the heat dissipation effect is poor, the utility model provides a high temperature resistant switch with efficient heat dissipation.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model provides the following technical solutions: a high-temperature resistant switch, including a switch body and a guardrail, a plurality of wiring holes are opened on the switch body, guardrails are installed on both sides of the switch body, and also includes a fan and a condenser. Two fans are installed on the top of the switch body, and a condenser is fixedly connected to the top of the switch body, and the condenser is located below the fan.

[0007] Furthermore, it also includes a connecting plate installed at the bottom of the switch body, the four sides of the connecting plate are fixedly connected to the first guide rod, the first elastic member is wound around the first guide rod, the first guide rod is slidably connected to the movable plate, and a plurality of card blocks are slidably arranged in the switch body, and each card block is slidably engaged with each movable plate.

[0008] Furthermore, it also includes cylinders installed on both sides of the switch body. There are two cylinders on both sides of the switch body. A connecting block is fixedly connected to the push rod of the cylinder. Two connecting rods are fixedly connected to the two connecting blocks on the same side, and sponge pads are installed on the connecting rods.

[0009] Furthermore, it also includes a plurality of second guide rods fixedly connected to the switch body, on which a baffle for covering the wiring hole is slidably arranged, and a second elastic member is wound around the second guide rod, and the second elastic member is used to push the baffle to cover the wiring hole.

[0010] Furthermore, a protective net is installed at the air inlet on the top of the switch body.

[0011] Furthermore, two wiping blocks are fixedly connected to the lower part of each side of the switch body.

[0012] Compared with the prior art, the switch provided by the embodiment of the utility model has the following advantages: 1. By starting the fan and the condenser, the fan draws external air into the switch body, and the condenser cools the drawn air at the same time. The cooled air is used to efficiently dissipate the heat of the electrical components inside the switch body, thereby achieving the effect of efficient heat dissipation for the switch body.

[0013] 2. By placing the switch body on the desktop, the card block slides upward along the switch body to disengage the movable plate from the card limit of the card block.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1: A high temperature resistant switch, see Figure 1 and Figure 2 As shown, it includes a switch body 1 and a guardrail 102. A plurality of wiring holes 101 are opened on one side of the switch body 1. Guardrails 102 are embedded on both sides of the switch body 1. The guardrails 102 can be used for exhaust and protection of electrical components inside the switch body 1. It also includes a fan 2 and a condenser 3. Two fans 2 are installed on the top of the switch body 1 by bolt connection. The top of the switch body 1 is fixedly connected with a condenser 3 by bolt connection. The condenser 3 is located below the fan 2.

[0026] When the switch body 1 needs to be used, the connection wire can be connected to the wiring hole 101. When the switch body 1 is in use, its own temperature will increase. At this time, by starting the fan 2 and the condenser 3, the fan 2 draws external air into the switch body 1, and the condenser 3 cools the drawn air. The cooled air is used to efficiently dissipate the heat of the electrical components inside the switch body 1, and the air inside the switch body 1 is dissipated outward through the through holes on the protective fence 102.

[0027] Example 2: Based on Example 1, refer to Figure 3 and Figure 4 As shown, it also includes a connecting plate 4 installed at the bottom of the switch body 1 by bolt connection, and the four sides of the connecting plate 4 are fixedly connected with the first guide rod 7 by welding. The first elastic member 8 is wound around the first guide rod 7, and the first guide rod 7 is slidably connected with a movable plate 6. The movable plate 6 slides horizontally along the first guide rod 7. The first elastic member 8 is used to push the movable plate 6 away from the connecting plate 4. Four card blocks 5 are slidably arranged in the switch body 1. The card blocks 5 slide up and down in the switch body 1, and each card block 5 is slidably engaged with each movable plate 6.

[0028] When the switch body 1 is placed on the desktop, the switch body 1 is affected by gravity and presses the card block 5 downward. At this time, the card block 5 slides upward along the switch body 1 to make the movable plate 6 break away from the clamping limit of the card block 5. At this time, each first elastic member 8 pushes each movable plate 6 to slide and disperse along the first guide rod 7 to the side away from each other. The floor area of ​​the bottom of the switch body 1 is increased by the movable plate 6, so that the center of gravity of the switch body 1 is moved downward to prevent the switch body 1 from tilting and displacement; when the switch body 1 needs to be carried, after the switch body 1 is lifted, each movable plate 6 is slid and reset toward the center along the first guide rod 7. At this time, the first elastic member 8 is compressed and deformed by force, and the card block 5 slides downward under the influence of gravity, so that the card block 5 is clamped with the movable plate 6. At this time, after the movable plate 6 is released, the movable plate 6 cannot slide on the first guide rod 7.

[0029] See also Figure 5 As shown, it also includes cylinders 9 installed on both sides of the switch body 1 by bolt connection. There are two cylinders 9 on both sides of the switch body 1. The top of the push rod of the cylinder 9 is fixedly connected with a connecting block 10 by welding. Two connecting rods 11 are fixedly connected to the two connecting blocks 10 on the same side by welding. A sponge pad 12 for wiping the guardrail 102 is installed on the side where the two connecting rods 11 are close to each other by bonding.

[0030] When the switch body 1 is in use, dust will adhere to the guardrail 102. To prevent the air outlet on the guardrail 102 from being blocked, the connecting block 10 is driven up and down by starting the cylinder 9. The connecting block 10 drives the connecting rod 11 to make the sponge pad 12 wipe the guardrail 102 up and down to remove the dust and impurities attached to the guardrail 102.

[0031] See also Figure 6 and Figure 7 As shown, it also includes a plurality of second guide rods 14 fixedly connected to the inside of one side of the switch body 1 by welding, and a baffle 13 for covering the wiring hole 101 is horizontally slidably arranged on the second guide rod 14, and a second elastic member 15 is wound around the second guide rod 14, and the second elastic member 15 is used to push the baffle 13 to cover the wiring hole 101.

[0032] When it is necessary to use a certain wiring hole 101 to connect a wire, the baffle 13 in the wiring hole 101 is slid to one side along the second guide rod 14. At this time, the second elastic member 15 is compressed and deformed by the force, and then the wire can be connected to the wiring hole 101. After the baffle 13 is loosened, the second elastic member 15 pushes the baffle 13 to resist the wire; when the wire is pulled out of the wiring hole 101, the second elastic member 15 loses the force and returns to its original state, thereby pushing the baffle 13 to slide back along the second guide rod 14 to reset, so that the baffle 13 blocks the wiring hole 101 to prevent dust and foreign matter from entering the wiring hole 101.

[0033] See also Figure 1 and Figure 6 As shown, a protective net 16 is embedded and installed at the air inlet on the top of the switch body 1; two symmetrical wiping blocks 17 are fixedly connected by bolts at the bottom of each side of the switch body 1.

[0034] The protective net 16 is used to prevent dust and foreign matter from being sucked into the switch body 1 by the fan 2; when the movable plate 6 slides and resets toward the center of the switch body 1 along the first guide rod 7, the edge of the movable plate 6 and the wiping block 17 produce friction contact, so that the dust and impurities sticking to the edge of the movable plate 6 can be scraped off.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
